In which type of chemical reaction do two or more substances combine to form one substance?

Chemistry
2 answers:
WINSTONCH [101]3 years ago
6 0

Explanation:

A reaction in which two or more substances combine together to form a single product is known as synthesis reaction.

For example, C + O_{2} \rightarrow CO_{2}

     or,        H_{2} + \frac{1}{2}O_{2} \rightarrow H_{2}O

During synthesis reaction, heat or light are released in the form of energy. Therefore, synthesis reactions are exothermic in nature.

hydrolysis of decapeptide P with the enzyme trypsin affords the following fragments: Glu-Gly-Lys, Gln-Val-Ile, Ala-Ser-Phe-Lys.
ehidna [41]

Answer:

The sequence of an amino acid P is:

Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile

Explanation:

Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named trypsin:

  • Glu-Gly-Lys,
  • Gln-Val-Ile
  • Ala-Ser-Phe-Lys

Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named chymotrypsin:

  • Lys-Gln-Val-Ile,
  • Glu-Gly-Lys-Ala-Ser-Phe

In order to determine the sequence of protein P , we will arrange fragments in such a way so that common fragments or the common parts of fragments should come under each other.

On arranging these fragments :

Glu-Gly-Lys-Ala-Ser-Phe

Glu-Gly-Lys

                   Ala-Ser-Phe-Lys

                                         Lys-Gln-Val-Ile

                                                Gln-Val-Ile

The sequence of an amino acid P is:

Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile

As the temperature of a gas increases, which of the following explains the effect on the average kinetic energy of the gas?
lidiya [134]
As the temperature of a gas increases, the kinetic energy of the gas particles will also increase. As the temperature of the gas increase, the gas particles gains more energy to move faster, they thus collide more with one another and with the wall of the container, thus increasing pressure as well. So, as the temperature of a gas increases, the kinetic energy increases and the pressure increases as well if the gas is inside an inflexible container.
